Key takeaways
- EPA WaterSense says to set vacation mode, bypass or unplug the softener, or turn off the house water for an extended trip, so salt and water are not wasted.
- SoftPro says trips of a few days to two weeks need no changes, and that a softener should stay in bypass for under 30 days.
- A typical regeneration uses 20 to 70 gallons of water, per EPA WaterSense, whether or not anyone is home.
- On a Fleck 5600SXT, the day override forces a regeneration after a set number of days, from Off to 99, even on a metered valve in an empty house.
- Quality Water Treatment programs its Fleck systems with a 14-day override, so they regenerate at least every two weeks.
- Where the softener can freeze, SoftPro's advice is to drain it, not bypass it.

What does water softener vacation mode do?
A vacation or away mode pauses or stretches out regenerations while the house uses little water, so the softener does not burn salt and water for nobody. EPA WaterSense lists it as the first option for an extended trip, alongside bypassing or unplugging the softener or shutting off the house water.
Valves that offer the setting describe it in their own manuals, and the sources behind this guide do not document any one maker's mode. Check what yours pauses and whether it still forces a regeneration. The common Fleck 5600SXT has no vacation button; you get the same effect with bypass or by leaving it running, as below.
What should you do with a water softener for a short trip?
For a trip of up to two weeks, leave the softener running. SoftPro's vacation guide (SoftPro, our store) says short trips usually need no changes and that a two-week break will not hurt the resin.
Before you go, top up the salt. EPA WaterSense suggests filling the brine tank about half full and never letting it drop below a quarter; keep the salt above the water line, and check for a crust with our salt bridge guide. The salt guide covers the level to aim for.
Does a softener regenerate when nobody is home?
A metered valve barely does, a timer valve does on schedule, and both regenerate when the day override is reached. The Fleck 5600SXT service manual describes how each control type decides.
| Control type (CT setting) | What triggers a regeneration | While you are away |
|---|---|---|
| Meter delayed (Fd) | Capacity used up, at the set regeneration time, or the day override | Rarely, unless the override days pass |
| Meter immediate (FI) | Capacity used up, at once, or the day override | Rarely, unless the override days pass |
| Time clock (tc) | Days since last regeneration equal the day override | On schedule, water used or not |
| Day of week (dAY) | Days switched "on" in the weekly schedule | On schedule, water used or not |
The Pentair 5600SXT manual allows a day override from Off to 99 days, and Quality Water Treatment programs its systems at 14. Each forced cycle still costs water: 20 to 70 gallons per EPA WaterSense, about 50 in Penn State Extension's estimate. NDSU Extension notes that recharging the beads too early wastes salt and water.
When should you bypass a water softener on vacation?
Bypass it for trips longer than two weeks, and keep it there for under 30 days. In bypass, water flows around the softener, so nothing passes through it and it does not regenerate. SoftPro warns that the house then gets hard water, so expect some spotting on fixtures when you return.
- Engage the bypass. On a Fleck plastic bypass, Quality Water Treatment turns both knobs clockwise toward BYPASS until they lock. See the bypass valve guide for other types.
- Confirm it. SoftPro runs a cold tap for a minute to check that the bypass is engaged.
- Do not force a stuck handle. SoftPro says forcing it can crack the valve body.
If you change a setting instead, such as the day override, write down the original value first. The settings guide and Fleck 5600SXT programming guide show where each setting lives.
What about trips longer than 30 days or a home that can freeze?
Shut the softener down properly instead of leaving it in bypass. SoftPro's limit of 30 days rules out a long bypass, and EPA WaterSense lists turning off the house water as an option for extended absences. Where the softener sits somewhere that consistently drops below 32°F, SoftPro's winterizing advice is to drain both tanks and the hoses.
For a vacation home, SoftPro goes further: drain the tanks, hoses and low points, leave a little salt in the brine tank, and consider shutting off and draining the whole house. Our guide on how to drain a water softener walks through each tank.
| Absence | What to do | Source |
|---|---|---|
| Up to two weeks, heated home | Leave it running with salt topped up | SoftPro, EPA WaterSense |
| Two weeks to 30 days | Bypass, or use the valve's vacation mode | SoftPro, EPA WaterSense |
| Over 30 days | Shut off the house water or drain the softener | EPA WaterSense, SoftPro |
| Location below 32°F | Drain tanks and hoses | SoftPro |
How do you restart a water softener after vacation?
Return the bypass to service, flush the cold lines, then check the clock and salt.
- Return the bypass to service. On a Fleck plastic bypass, turn the knobs counter-clockwise and make sure they are fully open, or hard water can slip past.
- Flush the cold taps first. SoftPro flushes cold lines before running the dishwasher or other hot-water appliances.
- Check the clock. A flashing time of day on a Fleck SXT means the power went out; any button press stops the flashing, and then you set the correct time. EPA WaterSense also says to check the programming after an outage.
- Let a missed cycle run. If the power failed when a regeneration was due, the Fleck control queues one for when power returns. Quality Water Treatment advises a manual regeneration after an outage; holding Extra Cycle for 5 seconds on a 5600SXT starts one at once.
- Top up the salt if the level dropped.
If you drained the softener, follow the restart steps in the draining guide instead. If the water feels hard a few days later, compare raw and softened samples as shown in how to tell if a water softener is working.
How we put this page together
Sources: SoftPro's vacation and winterizing guides, Quality Water Treatment's Fleck 5600SXT install guide and troubleshooting page, Pentair's two 5600SXT documents (the Fleck valve service manual and the VT system manual), EPA WaterSense, and Penn State and NDSU Extension, checked October 2026. We left out vacation-mode settings for valves whose manuals we did not read, SoftPro rental-property intervals that contradict each other on the same page, and power-backup hours, which differ between Fleck manual editions.
Common questions
Will my softener waste salt while the house is empty?
A timer valve regenerates on its schedule, so it keeps using salt. A metered valve uses very little but still regenerates when the day override is reached. Bypass or a vacation mode stops that for longer trips.
Why does SoftPro limit bypass to 30 days?
SoftPro links longer bypass to scale buildup and mineral spots, since the house runs on hard water the whole time. For longer absences, follow its vacation-home advice instead: drain the tanks, hoses and low points.
Is it worth unplugging the softener for a trip?
EPA WaterSense lists unplugging as one option for extended trips. When power returns, the Fleck manual says the time of day flashes; press any button and set the time, then check the settings.
What changes if a house-sitter is using water?
Nothing. With people in the house, leave the softener in service as normal and make sure there is enough salt for the time you are away.
Can the day override be turned off before a trip?
On a 5600SXT, yes: Pentair lists Off as a setting. With a metered valve and the override off, the softener regenerates only on water used. Write down the old value and restore it when you return.
Does a softener need a regeneration after sitting in bypass?
The sources give no rule for a normal trip. After a power outage, Quality Water Treatment advises a manual regeneration, and SoftPro's spring restart after winterizing includes one. Otherwise, return to service and let the valve run on schedule.
Should the water heater be turned down too?
That is outside the softener sources here. For the softener itself, SoftPro's one hot-water step is to flush cold lines before using hot-water appliances on your return.
